Why is it irrelevant? It's the only homeswest property in the street and the occupants have been causing trouble since they moved in. I told my brother previously that he should report them for antisocial behaviour but he was too slack.

Its relevant in the way it demonstrates your preconceived stereotype of homeswesters

Had its been "homeswesters" who had saved your cat from being pack raped by a bunch of feral tomcats I doubt you would have felt the need to mention it.
